FCC Notice

This equipment generates and uses radio frequency energy and, if not

installed and used in strict accordance with the manufacturer's

instructions, may cause interference to radio and television reception

which could void the user's authority to operate the equipment. It has

been tested and found to comply with the limits for a Class B digital device

pursuant to Part 15 of FCC Rules, which are designed to provide

reasonable protection against such interference in a residential

installation. However, there is no guarantee that interference will not

occur in a particular installation. If interference does occur, try to correct

it by taking one or more of the following measures:

λReorient or relocate the receiving antenna.

λIncrease the separation between the computer and the receiver.

λConnect the computer into an outlet on a circuit different from

that to which the receiver is connected.

λConsult the dealer or an experienced radio/television

technician for help.

Further, this equipment complies with the limits for Class B digital

apparatus in accordance with Canadian Radio Interference

Regulations.

Cet appareil numérique de la classe B est conforme au Règlement

sur brouillage radioélectrique, C. R. C., ch. 1374.

Introduction

The Seagate external CTT8000 SCSI minicartridge drive

is a fully integrated system that offers 4 Gigabytes (GB) of

native storage capacity with up to 8 GB of storage using

software data compression and the 3M Travan cartridge.

The drive provides a backup rate of up to 30

megabytes/minute (MB/min) without data compression in

a best case scenario with the system optimized1. Under

less than optimum conditions, transfer rates might range

from 18 to 28 MB/min. Given sufficient system resources

and compressible data structures, nominal transfer rates

of up to 60 MB/min may be observed using software data

compression (assumes 2:1 compression ratio).

The CTT8000 drive reads and writes the QIC-3080MC and

QIC-3095MC formats. The drive also provides a backward

read capability by reading the QIC 80,

QIC-3010, and QIC-3020 formats.

Seagate FastSenseTM enables the drive to automatically

sense the fastest supportable data transfer rate of the host

system and then chooses a transfer speed of either 600,

450, or 300 kilobytes/second (KB/sec). The drive meets

QIC-3080 and QIC-3095 specifications.

This manual guides you through connecting the external

SCSI Minicartridge Drive to your computer. Brief

operating instructions and maintenance guidelines are also

included in this manual. Figure 1 illustrates the drive.

1Actual performance on your system might vary and is dependent on the

system resources available and the structure and type of data compressed.

Before You Begin

Before you begin the installation, check to see that your

package contains the following hardware parts:

λTape drive unit

λExternal terminator

λExternal SCSI cable

λPower cable

λInstallation Manual

!Caution: Turn off your computer and the drive

before you begin the installation. Failure to do

so might result in damage to your equipment or

electrical shock to you.

Installation Manual Page 3

Cabling and Connectors

The drive provides standard, single-ended SCSI

transmission. ANSI SCSI standards specify the technical

requirements for correctly cabling and connecting single-

ended devices. The SCSI cable is supplied with the drive.

Single-Ended SCSI Connector

The External SCSI Minicartridge drive provides two 50-

pin, shielded connectors (ANSI Alternative 2) on the rear

panel of the drive.

These two connectors facilitate adding the drive to a daisy-

chain configuration. Either connector is a "SCSI IN"

connection; the other is a "SCSI OUT" connection. When

the drive is the last device in the chain (or the only

device), an external terminator is plugged in the "SCSI

OUT" connector. (Seagate P/N 38-9-74000000)

Installing the Drive

The External SCSI Minicartridge drive connects as a

turnkey subsystem to the computer. The drive may be

operated vertically or horizontally.

The default configuration for the drive is as follows:

λSCSI ID 2.

λTerminator power is supplied to the SCSI bus.

Page 4 Installation Manual

Installing these drives consists of a few easy steps:

1. Select an available SCSI ID.

2. Complete the interface cable connection(s).

3. Complete the power cord connection.

!Caution: Turn off your computer before you

begin the installation. Failure to do so might

result in damage to your equipment or electrical

shock to you.

Note: Write down the serial number and model

number shown on the drive and put this information

in a safe place. You need this information if you ever

call for service.

Selecting the SCSI Address

The rear panel of the external drive unit contains the

SCSI address selection push switch, the two interface

connectors, the ON/OFF switch, and the power cord

connection. Figure 2 illustrates the rear panel.

With the unit power OFF, locate the SCSI ID number

drive by pressing the + or - button until the desired

address (0 through 6) appears in the window. Then turn

power ON.

Completing the Interface Connection

The external drive provides two SCSI connectors to allow

daisy chaining. (See Figure 2.) Either connector can

connect to the host computer or any SCSI device in a daisy

chain.

Note: Turn off all power before connecting cables and

the terminator.

λWhen the drive is the last drive in the chain (or the

only drive), a single interface cable is attached to one

connector, and a terminating plug is installed in the

other connector. (Seagate P/N 38-9-74000000)

λWhen the drive is within the chain, the interface

cable from the preceding device is connected in one

connector; an interface cable is also connected from

the other connector to the following device. In this

case, no termination is used on the tape drive.

The same type of mating connector is used for either of the

daisy-chain connections. The mating interface connector

for the drive is a single-ended connector as described

earlier.

Connecting the Power Cord

See Figure 2 for the location of the power cord connector.

Insert the power cord mating connector into the connector

on the rear panel. Be sure the connection is secure. Plug

the other end of the power cord into an electrical outlet

power strip, a continuous power supply, or a wall

receptacle.

Loading and Unloading Cartridges

Your tape drive has a flip-up door that covers the cartridge

opening when a tape cartridge is not installed in the drive.

Once a cartridge is inserted, it is held firmly in place by the

drive's positive locking mechanism.

!Caution: DO NOT remove a tape cartridge

while the drive is active. Complete any tape

operations and wait until the green LED is OFF

before removing the cartridge.

To load a cartridge, insert it with the metal base plate down

and the tape access door facing into the drive. Figure 5

illustrates the loading of a cartridge.

Loading a Travan Cartridge

To unload a cartridge, wait until the drive activity LED is

OFF and then pull the cartridge straight out. Figure 6

illustrates the unloading of a cartridge.
